I have a form field called Zip and want to lookup/populate the city/state
fields
based on the zipcode entered. I'm thinking of using an onblur event to call
the
following JS function. Question how can I access the variable passed to the
JS
function inside a CF query? Is there a better way of accomplishing this
lookup?
<CFPARAM name="vZip" default="">
<CFINPUT TYPE="text" NAME="Zip" SIZE="5" MAXLENGTH="5"
onBlur="zipLookup(this.form.Zip)">
<script language="JavaScript">
function zipLookup(zipcode) {
if ((zipcode == "") || (zipcode.length < 5) || (zipcode.length > 5)) {
alert('Please enter a five digit zipcode!');
document.Log.zip.value = '';
document.Log.zip.focus();
return false;
}
else
</script>
????<CFSET vZip = <script language="JavaScript">zipcode</script>
>????
<CFQUERY name="qZipLook" datasource="dsn">
SELECT City, State
FROM tbl_zipcodes
WHERE zipcode = Trim(Variables.vZip)
</CFQUERY>
<CFIF IsDefined("qZipLook.RecordCount") AND qZipLook.RecordCount EQ
1
AND Variables.vZip is not "">
<script language="JavaScript">
document.Log.City.value =
'<cfoutput>#qZipLook.City#</cfoutput>';
document.Log.State.value =
'<cfoutput>#qZipLook.State#</cfoutput>';
</script>
</CFIF>
<script language="JavaScript">
return true;
}
</script>
thanks,
Dave
